Mathcad is computer software used to combine variables, text, and images into a worksheet. This allows for easy manipulation of inputs and expressions that update in real-time. It provides hundreds of functions for solving problems simply or complexly and can perform numerical or symbolic calculations quickly. Some key advantages include easy linking to other files, automatic unit conversion, plotting, simplifying expressions, solving equations and inequalities, and finding roots. While Excel is better for tables, Mathcad makes equations and calculations easier to write, understand and repeat with different parameters.

3. INTRODUCTION .

4. INTRODUCTION #1
Mathcad is computer software primarily
used to combine a variety of different
elements (variables, descriptive text, and
supporting imagery) into the form of a
worksheet, which is easy readable. This
allows for simple manipulation of input
variables, assumptions, and expressions,
which in turn update in real-time.

5. Mathcad provides hundreds of
operators and built-in functions for
solving technical problems from the
simple to the very complex. It can be
used to perform numerical calculations
or to find more general symbolic
solutions. In short time.
INTRODUCTION #2

6. First introduced in 1986
on DOS, it was the first to
introduce live editing of
typeset mathematical
notation, combined with its
automatic computations.

7. ADVANTAGES .

8. Advantages #1
Easy to link with cad ,
excel , pdf.. and other Files

11. Advantages #2
Using a smart Units,
easy convert to any
unit system.

12. You can attach units to every number or
variable used in Mathcad. Once a unit is
attached to a number or variable, Mathcad
remembers the unit. You can then display
this variable in any unit system.You do not
need to convert it. Mathcad does it for you
You can even mix unit systems .

14. Advantages #3
Easy plotting
2D&3D&polar curves,
graph fitting , contours
graph … ,

17. Advantages #4
Simplifying expressions can
make a differentiation
,integration , expand.., ) .

19. Advantages #5
Solving logical functions
and systems of equations
up to 50 equation and
unknowns .

20. Solve up to 50 simultaneous
equations in 50 unknowns .
Equations not restricted to
linear equations
Allows equations and
inequalities

23. Advantages #6
Finding roots of
quadratic and
polynomial equations

26. MATHCAD VS EXCEL .

27. MATHACD VS EXCEL
 Take a long time to
write the equations.
 Take a long time to
understand the
equations.
MATHCAD EXCEL
 Take a few time to
write the equations.
 Take a few time to
understand the
equations.

28. EXCEL…
 No “units” management
 Live calculation but formulae hard to
read
 No support for advanced math
calculations
 Calculus
 Differential equations
 Etc….

Right Tool for the Right Job: Mathcad versus Excel
MATHCAD …
Live calculations expressed in
natural, easy-to-read Math notation
Full support for units
Full support for advanced Math

31. DISADVANTAGES .

32. Disadvantages
Does not display tabular data as
cleanly as Excel.
Requires using a Mathcad
program to repeat the analysis
steps with different parameters.
